How can aphids and psyllids be controlled?
Chemical Control. Where psyllids or their damage are intolerable and insecticides will be applied, the most appropriate product will depend on the situation.

What is the parasitism rate of Asian citrus psyllid?
Parasitism rates of Asian citrus psyllid nymphs can be as high as 70% once the parasite establishes. However, the parasitism rate is not high enough to lower Asian citrus psyllid numbers sufficiently to prevent disease spread. Thus, releases are focused on residential citrus where areawide pesticide applications are difficult to achieve.
Where to find psyllids in a citrus tree?
